Try this. Unplug the USB device. Plug it back in, and as fast as you can start QEMU. 

My theory is another program might be using the device. This could be
Spotlight trying to index the drive.

Another possibility is libusb is not compatible with Mac OS 10.13 yet.

Do you have another computer that runs Mac OS 10.12 or under that you
can test on?
